    regular gates are made of aluminum, a wire gate is made of steel wire(just the gate, not the whole biner)
    All climbing brands make a model with a wiregate because it makes the biner weigh less. Less weight on the belt = more energy spent climbing harder.
    There is the rumored side-effect that in a rock impact, the solid gate might snap open due to its weight/momentum where a wire snapper is light enough to stay shut under the deceleration against a rock face, but nobody has ever heard of this happening. Anyway, in the end, I don't think its stronger, biners made for quickdraws are specced at ~20-25KN, anything more rugged is just unnecessary weight.

    Greg also sent replacement straps and a new hammock.
    The new hammock was unexpected and I think thats above and beyond. Greg didnt have to do that but I appreciate it.

    I consider this handled although anyone with the old biners should get new ones imo.
    My wife said she never saw me look more suprised than the moment I sat on the ground realizing what had occured. I would have not believed someone else had they told me it happend to them.
    I just wrote a very long post to inform you it isn't proper CE...

    The load rating of a carabiner is not equal to the breaking strength - there is a safety factor built in. In a non-climbing rated biner I would guess they target a small SF of 1.3 or so (fairly standard) to the YIELD point, NOT the breaking point. (Yeild point is where permanent deformation starts to occur, breaking point is when it actually breaks).

    The failure of these biner's is most likely due to a tighter hang angle than 30* - not implying these carabiners were appropriately speced for the application however, or the setup was negligent. My point is, I fully expect these biners would hold a load of 250lbs without breaking, until they fatigued and failed (also possible in this application).
    Every piece of hardware and webbing that I have is rated in WLL or SWL.

    SECTION 2.6 DESIGN FACTOR
    WARNING
    Never exceed the working load limit (WLL) of any synthetic web tie down(s). The loading of any
    synthetic web tie down beyond its WLL can result in severe personal injury or death. The tie down
    design factor is based on destructive, laboratory controlled testing conditions, which will not be
    exactly duplicated during actual loading conditions.
    2.6.1
    The design factor for new synthetic web tie downs with, or without hardware, shall be a min-
    imum of three (3) when tested in accordance with Chapter 3 of this Standard Specification.

    Each synthetic web tie down shall be marked or labeled, by the manufacturer, using an
    identification tag, stencil or other means with the following required information:
    The working load limit (WLL) of a synthetic web tie down shall be based on one-third (1/3) of
    the breaking strength
    of the complete assembly and not individual components.
    A synthetic web tie down shall not be subjected to loads greater than the working load limit
    (WLL) assigned by the manufacturer.
    Each manufacturer shall retain test data to verify breaking strengths. Destructive tests shall be
    conducted according to the test procedure outlined in Chapter 3 of this Standard Specification.

    My guess is, as in ISO certification in the aerospace industry, they do 6 month/annual audits sending a European Auditor to China to do the inspections so they keep their certification. But, I could be way off.
